Hydrothermal Synthesis of Lead Titanate and Lead Zirconate Titanate Electroceramic Particles
Chemical Engineering Communications, 2003 Hydrothermal synthesis of two lead-based perovskite powder systems, lead titanate and lead zirconate titanate, was investigated. Phase-pure perovskite lead titanate and lead zirconate titanate with various morphologies have been synthesized by hydrothermal methods at 150° and 175°C, respectively.

Fatigue of lead titanate and lead zirconate titanate thin films
Physics of the Solid State, 2008The fatigue of lead titanate and lead zirconate titanate ferroelectric thin films, i.e., a change in the polarization as a function of the number of switching cycles in an external electric field, is investigated experimentally. The threshold numbers of switching cycles are determined to be 1010–1011 for the lead titanate films and 109–1010 for the ...

Lead titanate and lead zirconate titanate piezoelectric glass-ceramics
Ferroelectrics, 1994Abstract The crystallization behavior and electrical properties of a piezoelectric glass-ceramic system consisting of lead titanate (PT) or lead zirconate titanate (PZT) in a lead borosilicate matrix is presented. Glass powders of compositions in this system densify at 650°C, and crystallize the ferroelectric PT or PZT phases.

Processing of porous lead titanate and lead zirconate titanate coatings
Le Journal de Physique IV, 1998Porous lead titanate (PT) and lead zirconate titanate (PZT) coatings were prepared by spin coating alkoxide solutions modified with benzoic acid. Carrying out the spin coating in a humid atmosphere (>30% RH) promoted the formation of porous microstructures. The variations in the chemical structure of the alkoxide and the coating microstructure indicate

Journal of Thermal Analysis and Calorimetry, 2004
Crystalline PbTiO3 was obtained through the thermal decomposition of 8-hydroxyquinolinate of lead(II) and that of titanium(IV), which was monitored by TG/DTG/DTA under different atmospheric conditions and with varying heating rates. The compound was prepared from adding 8-hydroxyquinoline solution in the solution of metallic ions Pb(II):Ti(IV) (1:1 ...

Dip-coating conditions and modifications of lead titanate and lead zirconate titanate films
Journal of Materials Science, 1990The modifications of dip-coated lead titanate (PT) and lead zirconate titanate (PZT) films strongly depend on the film thickness and the substrate in addition to the heat-treatment temperature. At 500 to 600 ° C, metastable paraelectric pyrochlore grew on glass plates (amorphous plates) when the thickness of the coated films produced by one coating ...

Switching Frequency Dependence in Thin Films of Lead Titanate and Lead Zirconate Titanate
Ferroelectrics, 2008The dependencies of coercive field and internal bias field on the frequency of the applied external field were experimentally studied in the films of lead titanate and lead zirconate titanate in a wide temperature range. It was demonstrated that with the frequency increase in the above films a build up of coercive field and internal bias field is ...

Refatigue of Ferroelectric Lead Zirconate Titanate
Journal of the American Ceramic Society, 2010Bipolar fatigue of ferroelectric lead zirconate titanate ceramics can be partly recovered by thermal annealing. For samples of initially, intermediately, or highly fatigued state, subsequent refatiguing yields a much more rapid decay in polarization and piezoelectric constant than the initially nonfatigued samples despite very ...
